How to configure IPv6 address in Linux
In this issue, the editor will bring you about how to configure IPv6 addresses in Linux. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.
Linux supports IPv6 after kernel version 2.2.0. Check whether the / proc/net/if_inet6 file exists to determine whether your system supports IPv6.
If not, try the following command to load the IPv6 module:
# modprobe ipv6
After successfully loading, you can use the IPv6 environment, and the system will automatically obtain the IPv6 address.
IPv6 related commands:
# ifconfig eth0 inet6 add 2001:da8:2004:1000:202:116:160:41/64 (manually add and configure fixed IPv6 address)
# route-An inet6 add default gw 2001:da8:2004:1000::1 (add default route)
# ping6 ipv6.scau.edu.cn
PING ipv6.scau.edu.cn (2001:da8:2004:1000:202:116:160:48) 56 data bytes
64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=0 ttl=64 time=0.020 ms
64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=1 ttl=64 time=0.019 ms
64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=2 ttl=64 time=0.014 ms
This display indicates that IPv6 has been configured successfully.
Linux Settings isatap Tunnel configuration IPv6
The Linux settings are as follows:
Ip tunnel add sit1 mode sit remote 192.168.253.49 local a.b.c.d
Ifconfig sit1 up
Ifconfig sit1 add 2001:da8:2004:2301:0:5efe:a.b.c.d
Route-An inet6 add:: / 0 fe80::5efe:192.168.253.49
Note: please use your real IPv4 address instead of the a.b.c.d above
After ifconfig is configured, you should see a V6 address prefixed with 2001:da8:2004:2301, hostid is 5efe:a.b.c.d, where a.b.c.d is your real IPV4 address.
